SASH-LOCK.

Specification of Letters Patent.

Patented Mar. 21, 1911.

Application filed December 3, 1910. Serial No. 595,335.

To all whom 'it may concern:

Be it known that I, TILLIAM K. DARE, a citizen of the United States, andresiding at Brooklyn, in the county of Kings and State of New York, haveinvented certain new and useful Improvements in Sash-Locks, of wiich thefollowing is a specification, such as will enable those skilled in theart to which it appertains to make and use the same.

This invention relates to sash locks and the object thereof is toprovide an improved device of this class which may be used as anordinary window sash lock, and which may be used as a door lock by meansof which a door may be locked or bolted on the inner side; a furtherobject being to provide a device of the class specified which is simplein construction and operation, conveniently manipulated, and which isalso comparatively inexpensive.

The invention is fully disclosed in the fol lowing specification, ofwhich the accompanying drawing forms a part, in which the separate partsof my improvement are designated by suitable reference characters ineach of the views, and in which Figure 1 is a sectional view showing oneside of a window frame and the bottom and top portions of the upper andlower sashes with my improved lock applied thereto; Fig. 2 a plan viewof the device as shown in Fig. 1; Fig. 3 a section on the line 33 ofFig. 2; and Fig. l; a partial section on the line 14 of Fig. 2.

In the drawing forming part of this specification, I have shown at a oneside of a window frame and at Z) a part of the upper sash, and at c apart of the lower sash, the bottom of the upper sash Z) being shown intrans verse section at If, and the top of the lower sash being shown intransverse section at 0 My improved sash lock consists of two parts oneof which is secured to the bottom of the upper sash and the other to thetop of the lower sash, and the part which is secured to the bottom ofthe top sash consists of a plate d provided with a raised jaw member dwhich ranges parallel with the glass 6 in the upper sash Z), and oneside edge of which is cut out to form a recess (Z and overhanging aw (Z*in the bottom of which and centrally of the aw member (Z is an apertured this construction being clearly shown in Figs. 1 and 1. The part whichis secured to the bottom of the lower sash consists of a main plate 6similar to the plate d, and which is secured on the top 0 of the lowersash c and provided centrally with a raised stud 6 having a nut 6Mounted on the plate 6 and rotatable on the stud e is a lock plate fwhich is oblong in form and in one side edge of the outer end portionthereof is a transverse recess f which forms a lock jaw f Mounted on andcountersunk in and longitudinally of the plate f is a longitudinallymovable lock bar 9, the outer end portion of which is provided with ahandle g and the inner end portion of which is provided with a bevelednose g and the stud 6 passes through a longitudinal slot 9 in the lockbar 9 and said lock bar is provided in the bottom side thereof with alongitudinal groove 9- in which is placed a spring 9. The plate 7' isalso provided on the bottom thereof with a stud or pin i which ismovable in a segmental groove i in the plate 6, and said groove and saidstud or pin serve to limit the swing of the plate f on said plate 6.

The operation will be readily understood from the foregoing descriptionwhen taken in connection with the accompanying drawing and the followingstatement thereof.

In the position of the parts shown in Figs. 1 and 2, the upper and lowersashes are locked together and cannot be lowered or raised. Whenever itis desired to manipulate the lock so that the upper sash may be loweredor the lower sash raised, the handle 9 of the lock bar 9 is graspedand-pulled outwardly against the operation of the spring This operationof said bar withdraws the nose g thereof from the overhanging jaw (F ofthe jaw member (2 and the plate 6 and lock bar 9 may be swung into thepositions shown in dotted lines in Fig. 2 and the upper and lower sashesmay be raised and lowered, or otherwise manipulated. When it is desired'to lock the sashes together as shown in Figs. 1 and 2, the upper sash bis raised and the lower sash 0 lowered into the position shown in Fig.1, and the plate f with the lock bar 9 is swung into the position shownin full lines in Fig. 2. In this operation, the jaw f of the plate 7engages the jaw member d as shown in Figs. 1 and 2, and the beveled nose9 of the lock bar 9 first strikes the head 61 of the jaw (Z and isforced outwardly and the spring 9 when the plate f with the lock bar gare swung fully into the position shown in full lines in Fig. 2, forcesthe bar .9 backwardly I are securclylocked together.

I or release the sashes the drawn outwardly and the plate. fiwithqthemember having in dotted lines in applied as a that the same 1 adapted tobe secured longitudinally of said lock vided at its outer end with sothat the nose 9 thereof'enters' cheap er ture (Z in'the jaw member (Z?and t-he'sashes It will be understood that the operation of the lock barg, when the plate f is swung into the position shown in full lines inFig.

2, is automatic, but in order toopen the lock Although,-

struction described maybe made, within'the scope of the appended claims,without departing from thespirit of myinvention or sacrificing itsadvantages. r I Q Having fully described my invention,

what I claim .as new'and desire to secure by Letters Patent, is j a r LAsash lock, comprising a jaw plate to the bottom of the upper sash and anoverhanging jaw in the bottom of which is an aperture, a main plateadapted ,to be secured on the top'of thelower sash, an OblOng lock platerotatably mounted on said main plate and provided at one end with a jawadapted to engage the jaw memher, on the lock plate, a longitudinallymovable lock bar countersunk in the top of and plate and proa handle andat its inner end with a beveled nose, and a spring placed beneath saidlock barand operating to force it outwardly.

QKA sash lock, comprising a jaw plate adapted to be secured to thebottom ofthe' 'upperxsash lock bar 9: must beprovided with a raised jawand provided with a raised jaw member havmg an overhanging aw in the amam plate bottom of which is an aperture,

' adapted to be secured on the top of the lower sash, an oblong lockplate rotatably mounted on said main'plate and provided at one end witha jaw adapted to engage the jaw member on the lock plate, alongitudinally movable lock bar countersunk in the top of andlongitudinally of said lock plate and 7 provided at its outer end with ahandle and at itsinner end with a beveled nose, and a. spring placedbeneath said'lock bar and operating to forceit outwardly, said lockplate and said main platebeing provided with means to limit the rotationof said lock plate.

3. A, sash lock comprising a jaw plate adapted to be secured "to thebottom of the upper sash and provided with a raised overhanging jawmember in the bottom of which is an aperture, amain plate adapted to besecured to the top of the lower sash, an oblong lock plate rotatablymounted on said main plateand provided at one end with a jaw adapted toengage the jaw member of said j aw plate, a longitudinally movable lockbar mounted on and movable longitudinally of said lock plate andprovided at one end with a handle, and the opposite end of which isadapted to enter the aperture in the overhanging jaw, and a tensiondevice for moving said lock bar in one direction.
